CROSS-REFERENCE TO RELATED APPLICATION

This application is a Section 371 National Stage Application of International Application No. PCT/CN2016/075326, filed on Mar. 2, 2016, entitled “ARRAY SUBSTRATE, METHOD FOR PRODUCING THE SAME, AND DISPLAY APPARATUS”, which has not yet published, which claims priority to Chinese Application No. 201510552742.X, filed on Sep. 1, 2015, incorporated herein by reference in their entirety.

BACKGROUND OF THE DISCLOSURE

Field of the Disclosure

The present disclosure relates to a technical field of display, more particularly, to an array substrate, a method for producing the same and a display apparatus.

Description of the Related Art

A flat display is classified into an emission flat panel display such as an organic light emitting display and a plasma display and a non-emission flat panel display such as a liquid crystal display.

The conventional flat panel display typically includes a display panel configured to display an image, a backlight module, a printed circuit board (abbreviated as PCB), and so on. A circuit on the PCB circuit board includes a timer control register (abbreviated as TCON) and a system on chip (abbreviated as SOC). At present, the development of the display panel is focused on the thinning of the display panel. The backlight module may have been attached completely onto the display panel to reduce the thickness. However, the PCB circuit board typically needs to be adhered to a backside (i.e., rear side) or other positions of the display panel by adhesive tapes to occupy a certain space in the module. Furthermore, the panel fabricator needs to purchase the PCB circuit board to assemble the module, thereby further reducing the profit of the products.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE DISCLOSURE

Examples of the array substrate, the method for producing the same and the display apparatus according to embodiments of the present application will be specifically explained below with reference to figures.

In the figures, the thicknesses and shapes of the respective layers are not intended to represent real scales of the array substrate, but intended to illustrate the disclosure in the present application.

An embodiment of the present application provides an array substrate. As shown in FIGS. 1a and 1 b, the array substrate 100 has a display region A and a driving circuit region B adjacent to the display region A.

The display region A and the driving circuit region B share a same base substrate 1. The driving circuit region B includes a timer control register 20 and/or a system on chip 30. The timer control register 20 is configured to achieve the timing control of the array substrate, and the system on chip 30 is configured to achieve the driving control of the array substrate.

It should be noted that the conventional circuit on the PCB includes the timer control register (TCON) and the system on chip (SOC). However, in the above array substrate according to the embodiment of the present application, the display region and the driving circuit region are formed on the same base substrate and the driving circuit region on the base substrate includes the timer control register and/or the system on chip. As a result, the driving circuit region may be considered to replace the PCB in the prior art such that the PCB may be omitted to achieve integration of display and circuit driving. Thus, the array substrate according to the embodiment of the present application is capable of reducing the thickness of the panel and achieving thinning of the module, so that it may be used in transparent display or super thin display. Further, the method for producing the array substrate according to the embodiment of the present application is helpful to save producing time and costs.

In an example, in the above array substrate provided by the embodiment of the present application, as shown in FIG. 1 b, the array substrate may include a thin film transistor, a passivation layer 4, a resin layer 5 and a common electrode line 6 located in the display region A and arranged in sequence on the base substrate 1. The array substrate may further include a first metal wiring 7, a first insulation layer 8 and a second metal wiring 9 located in the driving circuit region B and arranged in sequence on the base substrate 1. The array substrate may further include a timing control chip 22 (as shown in FIG. 1a ) and/or a system chip 32 (as shown in FIG. 1a ) electrically connected to the second metal wiring 9. The first metal wiring, the second metal wiring and the timing control chip may constitute the timer control register 20. The first metal wiring, the second metal wiring and the system chip may constitute the system on chip 30. In this way, all of layers located in the display region A and all of layers located in the driving circuit region B may be produced in the same base substrate 1 to achieve high integration and thinning of the module. The first metal wiring 7 and the second metal wiring 9 in particular are configured to connect the timing control chip or the system chip required for the driving circuit region to form the timer control register or the system on chip, and are configured to transmit signals provided by the timing control chip and/or the system chip to the display region. In an example, the second metal wiring 9 may have a surface used as a pad to form metal holes for welding the pins of electronic devices.

As an example, in the above array substrate provided by the embodiment of the present application, as illustrated in FIG. 1 b, the first metal wiring 7 located in the driving circuit region B may be a double layer structure. A gate electrode 2 of the thin film transistor in the display region A and a first layer structure 71 of the first metal wiring 7 located in the driving circuit region B are arranged in a same layer and made from same material. Further, a source electrode and a drain electrode 3 of the thin film transistor in the display region A and a second layer structure 72 of the first metal wiring 7 located in the driving circuit region B may be made from same material. Such design of double layers metal wirings, on one hand, may increase the thickness of a metal film to reduce the resistance of the metal wirings in the driving circuit region (the resistance in the driving circuit region is required to be lower than that in the display region), to improve the producing accuracy and integration. On the other hand, the second layer structure of the first metal wiring may be used to protect the first layer structure so as to prevent the first layer structure from being destroyed during etching process of the second layer structure. And no additional producing processes are needed upon producing the array substrate, but a pattern including the gate electrode and the first layer structure of the first metal wiring may be formed only through the same one patterning process and a pattern including the source electrode and the drain electrode and the second layer structure of the first metal wiring may be formed only through the same one patterning process. In this way, the producing costs may be saved and added value of products may be enhanced.

As an example, in the above array substrate provided by the embodiment of the present application, as illustrated in FIG. 1 b, the first insulation layer 8 located in the driving circuit region B may be a double layer structure. The passivation layer 4 in the display region A and a first layer structure 81 of the first insulation layer 8 located in the driving circuit region B may be arranged in a same layer and made from same material. The resin layer 5 in the display region A and a second layer structure 82 of the first insulation layer 8 located in the driving circuit region B may be arranged in a same layer and made from same material. Such design of double layers metal wirings may prevent signal interferences by adding the thickness of film of the insulation layer. And no additional producing processes are needed upon producing the array substrate, but a pattern including the passivation layer and the first layer structure of the first insulation layer may be formed only through the same one patterning process and a pattern including the resin layer and the second layer structure of the first insulation layer may be formed only through the same one patterning process. In this way, the producing costs may be saved and added value of products may be enhanced.

As an example, in the above array substrate provided by the embodiment of the present application, as illustrated in FIG. 1 b, the second metal wiring 9 located in the driving circuit region B may be a double layer structure. A common electrode line 6 in the display region A and a first layer structure 91 of the second metal wiring 9 located in the driving circuit region B may be arranged in a same layer and made from same material. A second layer structure 92 of the second metal wiring 9 located in the driving circuit region B is located above the first layer structure 91 of the second metal wiring 9 and it may be produced separately. Such design of double layers metal wirings, on one hand, may increase the thickness of a metal film to reduce the resistance of the metal wirings in the driving circuit region (the resistance in the driving circuit region may be required to be lower than that in the display region), to improve the producing accuracy and integration. On the other hand, the second layer structure of the second metal wiring may be used to protect the first layer structure to prevent the first layer structure from being destroyed during etching process of the second layer structure. And a pattern including the common electrode line and the first layer structure of the second metal wiring may be formed only through the same one patterning process. In this way, the process may be simplified, the producing costs may be saved and added value of products may be enhanced.

As an example, in the above array substrate provided by the embodiment of the present application, as illustrated in FIG. 1 b, the array substrate may further include a second insulation layer 10 with via holes 101 located in the driving circuit region B and arranged above the second metal wiring 9. The via holes 101 in the second insulation layer may be used for a pad patterned region for welding the subsequent chips, that is, the timing control chip or the system chip may be connected electrically to the second metal wiring 9 through the via holes 101 in the second insulation layer 10.
